A CORPORATION OF ILLINOIS ROOFING This invention relates to flexible roofing and has for its principal objects to improve the means for fastening the lower or exposed portions of overlapping courses against the tendency of the elements to raise them. In the preferred form here illustrated, this object is obtained by providing the adjacent` surfaces of the courses with complementary fasteners which automatically engage when forced together.

In the drawings Fig. 1 is a vplan view of a fragment of roof made with roofing strips embodying the invention;

Figs. 2 and 3 are sectional views taken on the lines 2-2 and 3 3 of Fig.l 1, respectively; and

Figs. 4 and 5.arel views similarto Fig. l illustrating the application of the invention in connection with roofing strips of different forms.

The roof shown in Fig. 1 is laid upon a suitable deck 10 (Fig. 3) and is composed .of strips, each of which includes a body portion 11 and a plurality of rectangular tabs 12 separated by narrow slots 13. Projecting from the lower surface of each tab ad-j jacent to the middle of its lower edge is a yielding element 14 of what is sometimes called a snap fastener. A complementary cup-shaped element 15 of such fastener -is carried by the upper face of the body portion 11 adjacent to the upper edge of each slot 13.

In laying the roof, the usual starting strip 16 is laid upon the deck 10 adjacent to the eaves and this strip may or may not be pro-- vided with the cup-shaped elements 15. The first course of strips is laid upon this starting strip with the tabs even with the'eaves. The cup-shaped elements l5 on this course form markers to indicate clearly the position of the next course and' it is avery simple matter to place the tabs of the next course and force the projections 14 into engagement I with the members 15. A single course of nails 17 is then inserted thru the body portion and into the deck. Each succeeding course is laid in like manner and the comb is finished with a cap in the usual manner.

The fasteners, therefore, not only serve to cffectually hold the tabs down, prevent curling or lifting by the wind, ice, etc. but they form very convenient guides to assist the workmen in laying the roof.

In Fig. 4 the strips include a body portion 18 and a plurality of tapered tabs 19 separated by spaces 2O of the same shape'and size of the tab whereby the roof is given the appearance of havingV been made from hexagonal shingles or4 tiles. With this form of strip, the fastener elements are located adjacent to the middle of the tabs at their lower edges and adjacent to the top of the spacing slots at their upper edges, the lines near the fastener elements corresponding in the complementary shapes of tabs and spacing recesses. Hence by having the cup-shaped members on the body portion adjacent to the top of the recesses and the projecting members on the tabs, the two elements will form markers for locating the successive courses and when pressed together, will securely fasten the ends of the tabs down.

In the form shown in Fig. 5, eachstrip includes a body portion 21 and a plurality of V-shaped tabs 22 but their lower ends cut away as indicated at 23. The tabs are separated by recesses of complementary shape and include a short line 24 corresponding to the out away corner 23. The complementary fastener elements -are carried adjacent to these short lines and perform the functions described above.

The fasteners shown can be readily made and inserted in the roofing strips by automatic machinery during the manufacture of the strips or as a separate operation. The snap fastener here shown is the preferred construction but it is obvious a variety of other forms can be used without departing from the spirit of the invention, and it is, therefore, intended .that such forms shallbe includedjin the following claims.

I claim as my invention:

of overlapping courses of flexible roofing matc-rial, each course including a lower exposed weather portion overlapping an upper portion of a course below, and a snap fastener for securing the exposed weather portion to 100 1. Aroof comprising a deck and a plurality I n cluding a plurality of spaced tabs, said tabs'l the overlapped portion of the course immediately below and including two elements, one carried by the underside of the overlapping portion and one carried by the upper side of 'overlapped"'portion and arrangedin stag-` gered relation with respect to the-other.

2. Flexible roofing in strip form comprisinga body portion and a plurality of spaced tabs proj etcing from one side of the body portion, snap fastener elements carried by the upper side of the body portion in alignment with the spaces between the tabs and complemental snap fastener elements carried by the underside of each tab adjacent to the middle thereof.

3. Flexible roofing in strip form comprising a body portion and a plurality of spaced tabs projecting from one side of the body portion, snap fastener elements carried by the upper side of the body portion in alignment with andadjacent the spaces between `the tabs and complemental snap fastener elements carried by the under side of each tab r adjacent to the middle thereof and adaptedto secure itself to the fastener element carried by the upper side of the body portionl when pressed together in a.' downward direction. Y

4. A roof comprising a deck and a plurality of overlapping courses of flexible roofing material, each course comprising a body portion'and alower exposed weather portion in-l overlapping the body portion of a course below, and a snap fastener for'securing the tabs to the body portion of theI course immediately below, and including two elements, one carried by the tabs and one carired by the 'overlapped body portion.

In testimony whereof I afzi my signature.
